Justin Timberlake has expressed disappointment in himself as a judge sentenced the pop star in his drink driving case.

The 43-year-old struck a deal and pleaded guilty to the lesser charge of impaired driving, stemming from his arrest in New York’s Hamptons in June.

The NYNCS singer-turned-solo star and actor appeared in Sag Harbour Village Court to face the music on Friday (US time).

Timberlake was fined $US500 ($745) with a $US260 surcharge, and ordered to complete 25 hours of community service at a non-profit of his choosing.

During the proceedings, Timberlake remained standing throughout and gave a statement expressing remorse.

“I did not live up to the standards that I try to hold for myself,” he said, adding that after reflecting on his arrest he found himself “in a position of disappointment”.

The married father-of-two said he grew up in a small town and appreciated the kind of strain his arrest had made on Sag Harbour.

Timberlake said he was “grateful for the opportunity to move forward” and use his platform to hopefully help others make “better decisions”.

“I should’ve had better judgment,” he said to the judge.

“I understand the seriousness of this.”

The pop star originally pleaded not guilty to a misdemeanour charge of driving while intoxicated and had his driver’s licence suspended during a hearing last month.

Timberlake was arrested in Sag Harbour, New York, a little after midnight on June 18 after police said he ran a stop sign in the village centre, veered out of his lane and got out of his BMW smelling of alcohol.

Police in court filings also said the Tennessee native’s eyes were “bloodshot and glassy” and that he had “slowed speech,” was unsteady on his feet and performed poorly on all sobriety tests.

Timberlake told the officer he had had one martini and was following some friends home, police said.

‘Mistake I made’

Outside court, Timberlake said he had learnt from his mistake and hoped others would too.

“What I’d like to say to everyone watching and listening, even if you’ve had one drink, don’t get behind the wheel of a car,” he said.

“There’s so many alternatives. Call a friend. Take an Uber. There’s many travel apps. Take a taxi.

“This is a mistake that I made, but I’m hoping that whoever’s listening and watching right now can learn from this mistake.

“I know that I certainly have… Even one drink. Don’t get behind the wheel of a car.”

His lawyer Edward Burke also addressed the media pack, noting that Timberlake had had “one drink in two hours at the American Hotel” before he drove.

“Contrary to what was reported, he wasn’t drinking other people’s drinks, or warned in advance not to drive,” he said.

“He wasn’t rude, he wasn’t obnoxious, he wasn’t belligerent.

“In fact, he was polite and he was cooperative and he was respectful during his entire encounter with law enforcement.”

Sag Harbour is a one-time whaling village mentioned in Herman Melville’s classic novel Moby-Dick that is nestled amid the Hamptons, an area of seaside communities about 160km east of New York City.

The 10-time Grammy winner has not publicly addressed the arrest but seemed to acknowledge it during a performance in Chicago just days later.

“It’s been a tough week,” he told the audience during the June 21 show at the United Center.

“But you’re here and I’m here. Nothing can change this moment right now.”

Timberlake has been on tour for months in support of his latest album.
